Re: [docbook-apps] nested indexterms

Thanks Bob,

I removed indexterm from systemitem until I could figure out something better.  Looks like this will just stay that way. 

Thanks,
Joy

Hi Joy,

I don't think what you are asking for is possible 
with DTD syntax.  In a DTD, an element can have only one content model, and 
it applies in all contexts that the element can appear in.  With DTD 
syntax, there is no way to say "systemitem allows indexterm in all contexts 
except when systemitem is a child of primary".  You would have to either 
ban indexterm from systemitem in all contexts, or ban systemitem from primary. 
And do the same with the other potential child elements of primary (and 
secondary and tertiary).

 

However, an XSL stylesheet can detect this problem 
using XPath and flag it as an error.  But that would not be part of the 
realtime validation that XML editors perform, so you would only discover a 
problem when processing the file.

Subject: [docbook-apps] nested 
  indexterms

  

I recently hit a problem with nested indexterms.  While 
  nesting an indexterm within an indexterm is invalid it seems there is a loop 
  hole.

If you put the systemitem tag within the primary tag then it 
  allows an additional indexterm which is valid in a systemitem tag.
I have 
  not tried other tags.

<indexterm>
  
  <primary>
   
  <systemitem>systemitem
     
  <indexterm>
       
  <primary>nested indexterm</primary>
     
  </indexterm>
    </systemitem>
  
  </primary>
</indexterm>

The validation process is not 
  catching this in Arbortext or saxon.  
I build html and pdf output and 
  it is only the PDF that is catching this with just a message but not breaking 
  the build.

java:         
  [error] no entries for index key nested indexterm'

I would like to 
  address this in the DTD so the writers can catch this when validating but do 
  not know where or how to state in the DTD to not allow nested indexterms once 
  you nesting tags.

I'm using Docbook 4.0 and I do have some 
  customizations already so it is not a problem to add to my custom 
  DTD.

Can someone help?

Thanks,
Joy
